MAYS LANDING — The Deptford Township man accused of stabbing a Hammonton mother and son to death in early November was at least a Facebook friend of one of the victims.

Patrick Latko

Patrick Latko, 32, is charged with double murder in connection with the stabbing deaths of 64-year-old Diana Patterson and her son, 29-year-old Ryan Patterson, in their South Madison Avenue home.

Latko was arrested Wednesday afternoon without incident at his home, according to a statement released by the Atlantic County Prosecutor’s Office.

The victims’ bodies were found in their home early on the morning of Nov. 3. An autopsy showed Ryan had suffered more than 20 stab and slash wounds, and his mother had sustained more than 10.

Latko is charged with two counts of murder, two counts of possession of a weapon and unlawful possession of a weapon.

Superior Court Judge Bernard E. DeLury has set bail at $2 million.

Listed as a 1998 Deptford High School graduate, Latko was a friend of Ryan Patterson’s on Facebook.

Latko is shown in his profile picture in a car with four others. A man tagged as Latko is in the back seat, and Patterson is driving.

Other Facebook photos from about a year ago show the two men had a connection through Pennco Tech, a school from which Patterson graduated in Blackwood as a diesel mechanic.

It was not immediately clear whether Latko was a fellow student there. A look through The Gloucester County Times archives revealed he was indicted in 2007 on an aggravated assault charge from West Deptford Township.

Patterson was an avid motocross racer, and when he wasn’t fixing engines he liked to ride his dirt bike with fellow enthusiasts.

Three days after his body and that of his mother were found, authorities found a knife in the yard of a residence on 12th Street, near the victims’ house. Investigators believe that’s the murder weapon, Atlantic County Prosecutor’s Office spokeswoman Haleigh Walz said.

The Atlantic County Sheriff’s Department and New Jersey State Police forensic services, along with police in Hammonton and Deptford Township, helped the Atlantic County Prosecutor’s Office with the investigation.
